The throngs of crowds passing through Exhibition Station to attend FIFA World Cup matches in Toronto have undoubtedly noticed a large lattice of steel taking shape over the rail corridor in recent weeks.
A new metal structure taking shape above the active rail tracks is the first permanent work on the future Exhibition Station transit hub, where existing GO rail routes will link up with the new Ontario Line subway.
The new 15.6-kilometre Ontario Line will run from this new multimodal hub at Exhibition Station up to the new Line 5 Eglinton in the northeast, and while construction isn't set to wrap up until the 2030s, you can already ride through this futuristic new rail terminal.
Permanent steel structural sections first appeared over the rail corridor in May, and work has continued to accelerate in recent weeks.
Metrolinx has shared a new time-lapse video highlighting the rapid assembly of these permanent structures, all as passenger trains zip through the growing network of columns.
Metrolinx explained on social media that more than 90 sets of these so-called "V-columns" will be installed over the course of the summer, which will set the stage for work on the new multimodal concourse.

Tunnelling recently launched just east of the growing Exhibition Station concourse building, and will eventually forge an underground path from this new landmark through the downtown core before the route surfaces to cross the Don River and proceed again north below city streets, emerging onto a massive bridge over the Don Valley and onto an elevated guideway into Thorncliffe Park.
